This post is the 13th in a series of posts about the adventure of building the world’s lightest brushless FPV quadcopter: project pepperF1SH.

New CFK arrived today — time to assemble the next bumper cage prototype! The last cage design was 2.83 grams, this cage only weights 2.4g (frame alone is 2.87 grams):

It is quite easy to assemble, take a 50cm round cfk rod, a matching cfk tube, and four printed holders. Still not 100% satisfied, I think I will have to modify the bumper holder to prevent twisting. I think I will move them to the motor mounts.

    Gefällt mir.
    Habe grad den Hoverbot Nano gebaut.
    Sollte Deiner es mal zu einer Kleinserie schaffen, wäre das ein tolles Gegenstück.

    Schöne Idee mit dem Carbonstab. Welchen Durchmesser habt der Stab im Querschnitt? Ich plane einen ähnlichen Aufbau, bin mir aber nicht sicher, ob ich 0,5 oder 1mm nehmen soll.

      Momentan sind sie 0.85mm. Das scheint ganz brauchbar zu sein. Crashtests stehen noch aus 😉
